[0024] In the following description, embodiments of the quick-release tray for circuit board aging testing according to the present invention will be described with reference to the accompanying drawings. Example 1

[0025] Figure 1-6 This invention illustrates a quick-release tray for circuit board aging testing according to an embodiment of the present invention. It includes: a heat-curing liner 2 installed within the inner cavity of a testing device 1; rectangular grooves 3 are provided on both the left and right sides of the inner cavity of the heat-curing liner 2; a rectangular hole is provided at the bottom of the inner cavity of the rectangular groove 3; a hollow rectangular block 4 is fixedly connected to the inner cavity of the rectangular hole; a rectangular limiting block 5 is slidably connected to the inner cavity of the hollow rectangular block 4; a spring 6 is welded to the bottom of the rectangular limiting block 5 and the inner cavity of the hollow rectangular block 4; a supporting rectangular rod 7 is slidably connected to the inner cavity of each of the two rectangular grooves 3; a rectangular limiting hole 8 is provided at the bottom of the front side of the supporting rectangular rod 7; and the surface of the rectangular limiting block 5 is slidably connected to the inner cavity of the rectangular limiting hole 8. A material tray 9 is fixedly connected between two supporting rectangular rods 7 in the cavity. A spring plate 10 is fixedly connected to the rear side of the inner cavity of the rectangular groove 3 by bolts. The rear side of the supporting rectangular rod 7 is slidably connected to the front side of the spring plate 10. With the setting of the spring plate 10, after the surface of the rectangular limiting block 5 disengages from the inner cavity of the rectangular limiting hole 8 and ends the limiting of the supporting rectangular rod 7, the supporting rectangular rod 7 can slide out of the inner cavity of the rectangular groove 3 more quickly under the spring push of the spring plate 10, so as to better facilitate subsequent testing. A trapezoidal head 11 is fixedly connected to the top of the rectangular limiting block 5, and the surface of the rectangular strip 14 is slidably connected to the inner cavity of the guide groove 13. Example 2

[0026] Figure 1-6This invention illustrates a quick-release tray for circuit board aging testing according to an embodiment of the present invention. It includes: a heat-curing liner 2 installed within the cavity of a testing device 1; rectangular grooves 3 are provided on both the left and right sides of the cavity of the heat-curing liner 2; a rectangular hole is provided at the bottom of the cavity of the rectangular groove 3; a hollow rectangular block 4 is fixedly connected to the cavity of the rectangular hole; a rectangular limiting block 5 is slidably connected to the cavity of the hollow rectangular block 4; a spring 6 is welded to the bottom of the rectangular limiting block 5 and the cavity of the hollow rectangular block 4; a supporting rectangular rod 7 is slidably connected to the cavities of both rectangular grooves 3; a rectangular limiting hole 8 is provided at the bottom of the front side of the supporting rectangular rod 7; and guides are provided on both the left and right sides of the cavity of the hollow rectangular block 4. The rectangular limiting block 5 has guide limiting blocks 12 welded on both sides. The surface of the guide limiting block 12 is slidably connected to the inner cavity of the guide limiting groove. By setting the guide limiting block 12, the rectangular limiting block 5 can slide in a straight line downwards during the sliding process in the inner cavity of the hollow rectangular block 4, and the rectangular limiting block 5 can maintain a smooth sliding. The hollow rectangular block 4 and the heat-melting liner 2 both have guide grooves 13 on their front sides. A rectangular strip 14 is fixedly connected to the front side of the rectangular limiting block 5, and a round rod 15 is fixedly connected to the bottom of the rectangular strip 14.

[0027] Working Principle: When using this invention, the user places the circuit board into the inner cavity of the material tray 9, then pushes the supporting rectangular rod 7, causing it to slide into the inner cavity of the rectangular groove 3. When the rear side of the supporting rectangular rod 7 contacts the surface of the trapezoidal head 11, the rectangular limiting block 5 slides downwards due to the special shape of the trapezoidal head 11 surface, thus compressing the spring 6. When the rear side of the supporting rectangular rod 7 contacts the spring plate 10, it continues to be pushed backwards. When the position of the rectangular limiting hole 8 aligns with the position of the rectangular limiting block 5, the rebound action of the spring 6 resets the rectangular limiting block 5, and the surface of the rectangular limiting block 5 slides into the inner cavity of the rectangular groove 3. The inner cavity of the limiting hole 8 fixes the position of the supporting rectangular rod 7. After the circuit board test is completed, the round rod 15 is pulled down and the rectangular limiting block 5 is slid down, so that the surface of the rectangular limiting block 5 is disengaged from the inner cavity of the rectangular limiting hole 8. When the surface of the rectangular limiting block 5 is disengaged from the inner cavity of the rectangular limiting hole 8, the elastic pushing force of the spring plate 10 makes the supporting rectangular rod 7 slide in the inner cavity of the rectangular groove 3, and the position of the rectangular limiting hole 8 is offset from the rectangular limiting block 5. Then the supporting rectangular rod 7 and the material tray 9 can be removed, which makes it easier to remove and replace the circuit board when it is being tested for aging, thereby improving the efficiency of subsequent testing.

[0028] In summary, this quick-release tray for circuit board aging testing aligns the rectangular limiting hole 8 with the rectangular limiting block 5 by pushing the supporting rectangular rod 7. Then, the spring 6 returns the rectangular limiting block 5 to its original position, and the surface of the rectangular limiting block 5 slides into the inner cavity of the rectangular limiting hole 8, thereby fixing the position of the supporting rectangular rod 7. This facilitates the removal and replacement of the circuit board during aging testing, thus improving the efficiency of subsequent testing.
